Cash Flow
Forecasting
What cash flow is and why it matters, cash flow forecasts, how to identify problems, and the difference between profit and cash — essential for IGCSE Business Studies.

The movement of money into and out of a business over a period of time. Cash flows IN when customers pay; cash flows OUT when the business pays suppliers, wages, rent, etc.
Cash flow is not the same as profit. A business can be profitable yet still run out of cash — for example, if customers pay on trade credit but suppliers demand immediate payment. Running out of cash is the most common cause of business failure, even for profitable businesses.

⚠️ Profit vs Cash — The Critical Difference
| Feature | Profit | Cash |
|---|---|---|
| What it is | Revenue minus all costs | Actual money available right now |
| When recorded | When sale is agreed | When payment is received |
| Trade credit effect | Profit recorded immediately | No cash until customer pays (30–90 days) |
| Can be positive | Yes — business profitable | No — cash negative if bills due now |
| Shown in | Income Statement | Cash Flow Forecast |
Key exam point: A business can be profitable but still fail due to poor cash flow. Profit is recorded when a sale is made — cash is only received when the customer pays. Trade credit causes this gap.
Quick Check — Inflow or Outflow?
Click each card to reveal whether it is a cash inflow or outflow.
A prediction of the cash inflows and outflows of a business over a future time period (usually month by month). It shows whether the business expects to have enough cash to meet its obligations.
Exam Note: You must be able to complete, read and interpret a cash flow forecast — including calculating net cash flow, opening balance and closing balance.
Structure of a Cash Flow Forecast
- Net Cash Flow = Total Cash Inflows − Total Cash Outflows
- Opening Balance = Closing Balance from the previous month
- Closing Balance = Opening Balance + Net Cash Flow

Closing balance = opening balance + net cash flow. A negative closing balance means the business has a bank overdraft — it cannot pay its bills. This is the red flag examiners look for.
Cash flow problems arise when a business cannot pay its bills on time — even if it is profitable. Understanding the root cause is essential before recommending a solution.
💡 Click Each Cause to Explore It
Click any card to reveal the full explanation and exam technique.
Cause: Customers buy on credit and pay 30–90 days later. The business records revenue as profit immediately but receives no cash until payment arrives.
Effect: Cash inflows are delayed → closing balance falls → business struggles to pay its own bills.
Exam tip: Always distinguish between when revenue is earned and when cash is received.
Cause: Business expands too quickly — buys too much stock, hires too many staff or takes on too many orders without sufficient cash reserves to fund the growth.
Effect: Cash outflows rise faster than inflows → negative net cash flow → cash crisis despite growing sales.
Exam tip: A fast-growing business is NOT automatically cash-healthy — rapid expansion often causes cash problems.
Cause: Revenue falls due to economic downturn, new competition or seasonal fluctuations (e.g. a ski resort in summer). Inflows drop while outflows stay the same.
Effect: Net cash flow turns negative — the business may need to borrow just to survive low-revenue periods.
Exam tip: Seasonal businesses plan for low-revenue months in their cash flow forecast — they need reserves or pre-arranged credit.
Cause: Large unplanned bills such as equipment repair, unexpected tax demands, wage increases or sudden rise in raw material costs drain cash reserves.
Effect: Outflows spike unexpectedly → closing balance falls sharply → potential overdraft.
Exam tip: A cash flow forecast allows businesses to anticipate large outflows and arrange finance in advance.
Cause: Business buys expensive machinery, property or vehicles using cash — a large outflow that reduces the cash balance immediately, even though the asset will generate returns over many years.
Effect: Major short-term cash drain → negative closing balance in the month of purchase.
Exam tip: This is why businesses use long-term finance (loans, leasing) for capital expenditure rather than using day-to-day cash.
Cause: The business fails to chase unpaid invoices, allows customers too long to pay, or sells on credit to unreliable customers who default.
Effect: Trade receivables (debtors) grow but cash does not arrive — inflows are permanently delayed or lost as bad debts.
Exam tip: “Improve credit control” is a valid solution — shorten payment terms, chase overdue invoices, use credit checks before offering trade credit.
Exam technique for causes: Identify whether the problem is on the inflow side (too little cash coming in) or the outflow side (too much cash going out). This determines the right solution.
A cash flow problem identified in a forecast should be addressed before it becomes a crisis. Solutions either increase inflows, reduce outflows, or delay outflows.
| Solution | How It Helps | Possible Drawbacks |
|---|---|---|
| Bank overdraft | Short-term borrowing to cover temporary shortfall. Quick to arrange, flexible. | High interest rate; repayable on demand; not suitable for long-term problems. |
| Short-term bank loan | Fixed amount borrowed and repaid over an agreed period. More structured than overdraft. | Interest costs; may require collateral; adds to liabilities. |
| Reduce credit given to customers | Shorten payment terms (e.g. 30 → 14 days) to speed up cash inflows. | May lose customers to competitors offering better trade credit terms. |
| Negotiate longer credit from suppliers | Delay outflows — pay suppliers later (e.g. extend from 30 → 60 days). | May damage supplier relationships; suppliers may refuse or charge more. |
| Sale of assets | Sell unused or non-essential assets for immediate cash inflow. | Loss of productive capacity; may be sold below market value; one-off solution. |
| Sale and leaseback | Sell an asset (e.g. property) and immediately lease it back — raises cash while retaining use. | Ongoing lease costs; business loses ownership; long-term cost may exceed asset value. |
| Cut costs / reduce outflows | Reduce unnecessary spending — delay non-essential purchases, renegotiate contracts. | May harm quality, morale or long-term growth if cuts are too deep. |
| Increase sales revenue | Boost inflows through promotions, discounts or new customers. | Revenue takes time to materialise; discounting reduces margins. |
🎯 Activity — Match the Solution to the Problem
Read each scenario and choose the most appropriate solution.
BrightBakes Ltd sells cakes to supermarkets on 60-day trade credit. Its own rent ($3,000) is due within 7 days but its cash balance is only $800. The supermarkets owe $28,000 but won’t pay for 50 more days.
FixIt Plumbers has a fleet of vans and unused office premises worth $150,000. Cash is very tight and it is struggling to pay wages this month.
SunTours holiday company earns 80% of its revenue in June–August. In January–March the cash balance turns negative as rent and wages continue but sales are minimal.
Exam technique for solutions: Match the solution to the cause. If the problem is slow-paying customers → reduce credit period or use debt factoring. If the problem is high outflows → cut costs or negotiate longer credit from suppliers. Always explain why the solution works AND state a drawback.
| Topic | Key Point |
|---|---|
| Cash Flow | Movement of money in and out of a business — not the same as profit |
| Cash Inflow | Money received: cash sales, loans, sale of assets, owner investment |
| Cash Outflow | Money paid out: wages, rent, stock, tax, loan repayments |
| Net Cash Flow | Total Inflows − Total Outflows for the month |
| Opening Balance | Cash balance at the start of the month = previous month’s closing balance |
| Closing Balance | Opening Balance + Net Cash Flow — negative = overdraft = problem |
| Cash Flow Forecast | Prediction of inflows and outflows over future months — used to plan ahead |
| Profit vs Cash | Profit recorded when sale made; cash received when customer pays. Trade credit creates the gap. |
| Causes of problems | Slow-paying customers, overtrading, falling sales, high expenses, over-investment in assets |
| Solutions | Overdraft, bank loan, reduce credit to customers, negotiate longer supplier credit, sell assets |
Profit is recorded when a sale is agreed. Cash arrives when customer pays. Trade credit causes the gap.
The business has a shortfall — it owes more than it has. Action needed: overdraft, cut costs, sell assets.
Growing too fast without enough cash to fund it. Even a profitable expanding business can run out of cash.
Bank overdraft — flexible and quick. But expensive and repayable on demand. Not a long-term solution.
Sell an asset, then lease it back. Raises immediate cash while keeping use of the asset. Long-term cost is higher.
Identify inflow vs outflow problem → choose matching solution → explain how it helps → state one drawback.
Top 4 Exam Tips: (1) Cash flow ≠ profit — examiners test this distinction constantly. (2) Negative closing balance = overdraft = financial danger. (3) Always identify whether the problem is inflow or outflow before recommending a solution. (4) A cash flow forecast helps businesses plan ahead and arrange finance before a problem hits.
NovaCraft Ltd: Opening balance Jan = $8,000. Total inflows Jan = $35,000. Total outflows Jan = $42,000.
- Net Cash Flow: $35,000 − $42,000 = ($7,000) negative ✓
- Closing Balance: $8,000 + (−$7,000) = $1,000 ✓
- Analysis: Although positive, $1,000 closing balance is dangerously low — any unexpected outflow next month would create an overdraft ✓
GreenGrow Ltd supplies garden centres on 60-day trade credit. Its closing balance is forecast to be ($12,000) in March. A bank overdraft has been suggested as a solution.
- Cause: GreenGrow sells on 60-day credit — cash inflow delayed by 2 months while outflows (wages, stock) continue monthly ✓
- Effect of cause: Inflows insufficient to cover outflows in March — closing balance turns negative ($12,000 overdraft) ✓
- Solution — overdraft: A bank overdraft immediately covers the shortfall — the business can pay wages and suppliers ✓
- Benefit: Flexible, quick to arrange, only pay interest on the amount used ✓
- Drawback: High interest rate, repayable on demand — if the bank recalls it suddenly, GreenGrow is worse off ✓
- Evaluation: The overdraft is a good short-term fix, but the underlying problem (60-day credit) will recur. A more sustainable solution would be to shorten the credit period to 30 days — this addresses the root cause and permanently improves cash flow ✓
